A latex product composition that includes an anionicaily-stabilized latex; at least one volatile base compound; and one or more water soluble, polymers or polymeric adducts that have a backbone with a plurality of amine functional groups and hydroxyl functional groups. The polymers or polymeric adducts may be an addition product formed from at least one multifunctional amine compound reacted with one or more polyfunctional epoxy compounds, one or more monofunctional epoxy compounds, or a combination thereof. The polymers or polymeric adducts are formed by the addition reaction of the amine compound and the one or more epoxy compounds with 1.3 to 3.8 amine functional group per epoxy functional group. The addition product may be present in about 0.1 to 15.0 wt. % and the at least one volatile base compound is present in about 1.0 wt. % to 10.0 wt. % based on the weight of the particles present in the anionicaily-stabilized latex.

Latex products having polymers and polymer adducts as quick-setting additives

Latex binders useful for preparing zero or low VOC coating compositions having excellent freeze-thaw stability, good tint strength and good scrub resistance when cured may be obtained using a polymerizable polyalkylene glycol monomer such as polyethylene glycol methacrylate in combination with one or both of an emulsifier or a polymerizable polyalkylene glycol monomer containing bulky hydrophobic groups substituted on an aromatic ring.

Latex binders useful in zero or low VOC coating compositions

The instant invention is a polyurethane dispersion, method of producing the same, coated articles, and method for coating articles. The polyurethane dispersion according to the present inventions includes (a) one or more polyurethane units derived from one or more prepolymers wherein the one or more prepolymers comprise the reaction product of a mixture dissolved in dipropylene glycol dimethyl ether in the presence of one or more first surfactants with one or more isocyanates, wherein the mixture comprises one or more natural oil based polyols, and one or more adipate polyols, and optionally one or more short diols; and (b) water.
